# 木工胶要用多少？涂胶量、接缝与成本

胶合面积乘以 g/m² 涂胶量：拼板、板材组坯、指接和贴面作业的胶粘剂用量实证算法。

## 涂胶量模型

胶粘剂技术数据表都以每平方米胶合面的克数（涂胶量）给出用量，而这一个数字决定了一切：用胶量 kg = 面积（m²）× 涂胶量（g/m²）× 涂胶面数 × 损耗系数。PVAc D3 单面涂胶约 175 g/m²（Jowat 103.70 标注 175 ± 25）；两个配合面都涂则翻倍。[木工胶用量](https://nestingcalc.com/cn/wood-glue-calculator/) 实现的正是这个模型，内置数据表预设值，每个字段都可按你自己的压合记录改写。

## 拼板：把接缝数出来

对实木拼板来说，胶合面就是接缝，而接缝是可以数的：一块 1220 mm 宽的板由 40 mm 板条拼成，有 31 根板条、30 道接缝，每道接缝都是一条“板长 × 板厚”的胶合带。折算下来，每平方米板材约有 0.44 m² 胶合面积。按实木拼板 200–300 g/m² 的涂胶量，每平方米板材耗胶 86–130 g——也就是每立方米成品拼板约 4.8–7.3 kg 胶，这个数字生产计划员可以直接拿去采购。

## 贴面层压与组坯

面层胶合按胶合面层数成倍增加：三层组坯有两个胶合面，因此一套 2440 × 1220 mm 的板需要为 5.95 m² 的面积涂胶。正交胶合木（CLT）、门板贴面和弯曲层压都遵循同一条计数规则。[木工胶用量](https://nestingcalc.com/cn/wood-glue-calculator/) 设有面层层压模式，输入板材尺寸、层数和组坯套数即可，涂胶面选项则决定你是单面涂还是双面涂。

## 指接、单板和难算的情形

指接是车间里涂胶量最高的工序——PUR 体系标注 430–630 g/m²，因为齿形把有效表面积翻了一倍。酚醛胶膜和单板压贴为每胶层 150–300 g/m²，配方中带填料时升到 180–240。桉木生材配 PU 约为 210 g/m²。如果你的情况都对不上，那就实测：一个班次前后各称一次胶桶，再除以这一班做出的接缝数量。

## 从克数到采购订单

胶按公斤买，却按体积储存和计量，所以最后一步是密度：PVAc 约 1.08 g/cm³，PU 介于 1.1 与 1.2 之间。按 1.08 计算，一批 20 m² 作业所需的 4.2 kg 胶等于 3.9 升——一桶 5 kg 装还有余量。在 [木工胶用量](https://nestingcalc.com/cn/wood-glue-calculator/) 里填上你的每公斤单价，每份报价就带着真实的胶粘剂成本，而不是辅料里的一个四舍五入。
